Duroflex Joint Revealed
The MetalCloak Duroflex Joint takes the best qualities of OEM style Clevite Joint and the popular Johnny Joint style Flex Joint and combines them.
We tested our Duroflex Joint using a "Shaker Table" and seismometer app to show how much Vibration Dampening the Duroflex Joint gives you compared to other industry leading joints.

What is Corner Travel Index?

FMVSS 126 Compliant
MetalCloak not only has the best off road flex, but we are also Federal Motor Vehicle Safety Standard 126 certified and compliant. No other company can match our on- and off-road performance.
IT ALL STARTS WITH THE BUSHINGS
The Patented Duroflex™ Joint (metalcloakpatents.com) is the key to getting the greatest flex in a bolt-on suspension kit. Period.
MetalCloak has taken the best features of the most widely used control arm joints and combined those features to create the Duroflex Joint, producing a Low-Maintenance, High-Misalignment (34˚), Self-Centering, Rebuildable Joint with an OEM quality ride.
Now with Kevlar!
DuPont™ Kevlar® Fiber is now compounded in the proprietary elastomer of the Duroflex Bushing, bringing even more strength, durability and performance.
Kevlar® is a synthetic fiber with extremely high tensile strength to weight ratio…five times stronger than steel and commonly used in bullet proof armor applications.
Duroflex Bushings w/Kevlar® can be identified by the MetalCloak “M” located on the outer surface.
The Duroflex Joint Provides The Best Ride. Period.

By adapting the High Transverse Flex characteristics of a typical Flex Joint, the Duroflex Joint gives you...
